About
I began my career at the University of Murcia, graduating in 2019 with a BSc in Physics [link]. After graduation, I studied an interuniversity master’s degree in Photonics Science [link] with the participation of the University of Barcelona, Polytechnic of Catalunya, Autonoma of Barcelona, and the Institute of Photonic Sciences (UB, UPC, UAB, ICFO). Once finished, I obtained a PhD position in the Applied Optics Group at the University of Kent [link] under the Marie Skłodowska-Curie Actions.
Under the supervision of Prof. Adrian Podoleanu, I’ve been involved in the European project “Next Generation of Tunable Lasers for Optical Coherence Tomography” [link]. During my PhD, my research has been focused on swept sources for optical coherence tomography (SS-OCT). Optical coherence tomography is a non-invasive 3D high-resolution imaging technique, which in its last modality uses tunable sources to generate depth scans. The characteristics and performance of the source will strongly determine the quality of the images acquired. Strong efforts have been made in the latest years (2010-2020) towards ultrafast, and ultralarge bandwidth sources. Sources based on time-stretch are a great solution for high-speed imaging, however high-speed comes with several challenges to address. Moreover, for this kind of sources, broadband mode-locked lasers are used, so different mode-locked lasers based on nonlinear polarization rotation are examinated as candidates for swept sources seed. During my PhD I research on time-stretch sources, mode-locked lasers, MEMS-VCSEL and try to overcome some of the problems that high-speed optical coherence tomography brings.
Professional
Bachelor’s degree Physical Sciences at the University of Murcia. The following year I started an interuniversity master’s degree in photonics with the participation of the University of Barcelona, Polytechnic of Catalunya, Autonoma of Barcelona (UB, UPC, UAB) and the Institute of Photonic Sciences (ICFO) where I was able to learn from the world top researchers (Prof. Dr Niek Van Hulst, Prof. Dr. María García-Parajo, Prof. Dr. Jens Biegert) in different fields such as non-linear optics, ultrafast, biophotonics.
